Any technology that uses chemical methods to change the composition, structure or synthesize new substances belongs to chemical production technology, that is, chemical process, and the obtained product is called chemical or chemical product. The mixing device is one of the indispensable devices in chemical processing, which is an instrument for mixing and stirring two different chemical materials in proportion.

[0003] At present, most of the raw material premixing devices for chemical processing on the market will appear solidification after stirring and mixing for a long time, resulting in a large amount of raw material waste, expanding people's economic loss, increasing people's capital cost investment, and bringing inconvenience to the work of workers.

[0005] The above-mentioned raw material premixing device can continuously stir the chemical raw materials through the stirring equipment arranged therein, thereby avoiding the solidification of the chemical raw materials. However, the stirring frame needs to be continuously stirred during the stirring and anti-solidification process. First of all, continuous stirring consumes a large amount of energy. The scale of chemical production is often large, and long-term high-energy operation significantly increases production costs. For some chemical raw materials sensitive to shear force, excessive and continuous stirring may cause changes in the physical or chemical properties of the raw materials, such as breaking of the molecular chains of high-molecular polymer raw materials, inactivation of certain active ingredients, etc., thereby reducing the quality of the raw materials and the performance stability of the products, affecting the quality and application effect of the chemical products.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Please see Figures 1-6This utility model provides a technical solution: a raw material premixing device for chemical processing, comprising a stirring drum 1 and a stirring frame 2, including,

[0031] Servo motor 301 is connected to the top of stirring drum 1, and stirring rod 302 is connected to the drive end of servo motor 301;

[0032] An arc-shaped block 303 is positioned above the servo motor 301, and an arc-shaped groove is formed inside it. One end of the stirring rod 302 is slidably connected to the groove.

[0033] The first connecting plate 304 is connected to the side of the arc block 303 located on the inner arc. A contact switch 307 is provided on one side of the first connecting plate 304, which is located on the moving path of the first connecting plate 304 and is used to control the stirring state of the stirring rack 2.

[0034] It should be noted that the bottom of the mixing drum 1 is connected to a drive motor 10 to drive the mixing rack 2 to rotate, and the contact switch 307 can be a self-locking switch or a bistable switch.

[0035] In practice, starting the servo motor 301 can drive the stirring rod 302 to rotate, causing the stirring rod 302 to slide within the groove opened in the arc block 303. As the stirring rod 302 slides, the arc block 303 can drive the first connecting plate 304 to reciprocate intermittently. When the arc block 303 drives the first connecting plate 304 to the position of the contact switch 307, the contact switch 307 is triggered, causing the stirring rack 2 to enter an intermittent period and temporarily stop stirring the raw materials. When the contact is triggered again, the stirring rack 2 will be triggered to stir again. This setting allows the stirring rack 2 to stir and mix the raw materials in an intermittent manner, which not only ensures the uniformity of the raw material mixing, but also avoids problems such as energy waste and excessive wear of equipment caused by over-stirring.

[0036] See Figure 2 A mounting frame 305 is provided on one side of the first connecting plate 304. A sliding plate 5 is slidably connected inside the mounting frame 305. A first return spring 306 is connected to one side of the sliding plate 5. The other end of the first return spring 306 is connected to the mounting frame 305.

[0037] In practice, the sliding plate 5 is designed to facilitate contact with the contact switch 307, while the first reset spring 306 is designed to facilitate the return of the sliding plate 5 to its original position during the process of not contacting the first connecting plate 304.

[0038] See Figure 5 The mounting frame 305 has two symmetrical guide rods 6 connected inside. The slide plate 5 is slidably connected to the guide rods 6, and the slide plate 5 has a sliding opening that matches the guide rods 6.

[0039] In practice, the guide rod 6 can limit and guide the sliding of the skateboard 5, further improving the stability of the skateboard 5 during the sliding process.

[0040] See Figure 5 The top of the mixing drum 1 is connected to a mounting bracket 8, and the top of the mounting bracket 8 is detachably connected to a limiting frame 4. The first connecting plate 304 is slidably connected within the limiting frame 4.

[0041] In practice, the mounting bracket 8 facilitates the installation of the limiting frame 4.

[0042] refer to Figure 6 It also includes,

[0043] At least two limiting clamps 701 are symmetrically slidably arranged on both sides of the limiting frame 4. The bottom of the limiting clamp 701 is connected to a second connecting plate 702. The limiting clamp 701 is vertically arranged on the top of the second connecting plate 702. The bottom of the mounting bracket 8 is rotatably provided with an abutment plate 703 for driving the limiting clamp 701 to move vertically downward.

[0044] In practice, by replacing the arc-shaped blocks 303 with different curvatures, the frequency of intermittent start-up of the mixing rack 2 can be easily controlled. During use, the position of the limiting frame 4 can be limited by the set limiting clamp 701. By rotating the abutment plate 703, it can be made to no longer abut against the second connecting plate 702. At this time, the limiting effect of the limiting clamp 701 on the limiting frame 4 can be released, making it convenient to replace the arc-shaped blocks 303.

[0045] refer to Figure 6 The limiting clamp 701 is connected to a second reset spring 704, and the other end of the second reset spring 704 is connected to the top of the mounting bracket 8.

[0046] In practice, the second reset spring 704 facilitates the automatic spring-back reset of the limit clamp 701, making it easy to disassemble the limit frame 4.

[0047] refer to Figure 6 A connecting rod 705 is connected to one side of the contact plate 703, and the other end of the connecting rod 705 extends to the outside of the mounting bracket 8.

[0048] In practice, the connecting rod 705 facilitates the application of force to rotate the contact plate 703.

[0049] refer to Figure 1 A discharge cylinder 9 for discharging materials is provided on one side of the bottom of the mixing drum 1.

[0050] In practice, the discharge cylinder 9 is designed to facilitate the discharge of premixed raw materials.

[0051] Working principle: Starting the servo motor 301 drives the stirring rod 302 to rotate, causing the stirring rod 302 to slide in the groove opened in the arc block 303. As the stirring rod 302 slides, the arc block 303 drives the first connecting plate 304 to move back and forth intermittently. When the arc block 303 drives the first connecting plate 304 to the position of the contact switch 307, the contact switch 307 is triggered, causing the stirring rack 2 to enter an intermittent period and temporarily stop stirring the raw materials. When the contact is triggered again, the stirring rack 2 will be triggered to stir again. This setting allows the stirring rack 2 to stir and mix the raw materials in an intermittent manner, which not only ensures the uniformity of the raw material mixing, but also avoids problems such as energy waste and excessive wear of equipment caused by over-stirring.

[0052] By replacing the arc-shaped blocks 303 with different curvatures, the frequency of intermittent start-up of the mixing rack 2 can be easily controlled. During use, the position of the limiting frame 4 can be limited by the set limiting clamp 701. By rotating the abutment plate 703, it can be made to no longer abut against the second connecting plate 702. At this time, the limiting effect of the limiting clamp 701 on the limiting frame 4 can be released, making it convenient to replace the arc-shaped blocks 303.
